Cpanel New install problems

So I am somewhat of a newbie, I have been working with cpanel for years but in limited capacity (IE godaddy hosting accts etc) So recently I have been moving to my own server for web hosting. That being said this is where I become the newbie... So I got cpanel and whm installed on centos 7.8. I have 4 static Ip addresses that are associated with this server one per nic. so here are the problems I have arising at the moment. modem firewall, router firewall, and server all have had their firewalls disabled. I seldomly can access the xxx.xxx.xxx.xxx:2087 from another computer on the same network. I keep getting comm error when trying to add iP addresses within cpanel. I cannot submit a ticket from the server Cpanel staff cannot access via ssh Can anyone here provide some guidance on what is causing this assumed network error. Additionally I have gotten emails about these multiple times The service "ipaliases" appears to be down. DNS resolver failure
